Jenny, once a timid girl who suffered relentless family abuse in her past life, is given a second chance at existence. Reborn into the powerful Brennan family as the cherished daughter of Duke Brennan, she carries with her the pain of her previous life but also the determination to live differently. As she enters the prestigious Royal Academe, Jenny finds herself once again crossing paths with the enigmatic crown prince, a young man burdened by *mana aggression* caused by his rare condition-the *triple mana heart*. Their uneasy alliance slowly grows into trust as circumstances force them to work together. Strange events soon unravel within the walls of the Academe. Whispers of betrayal and the presence of a hidden spy threaten both the students and the kingdom itself. Jenny, the crown prince and her brother will expose the infiltrator, defend the Academe from a looming invasion, and protect the fragile peace of the realm. Yet, as the crown prince digs deeper, he stumbles upon a terrifying truth: the web of black magic not only fuels the invasion but is also tied to the assassination of his parents. The revelation will test his strength and resolve, Jenny's determination, and their bond, as they stand at the crossroads of destiny-fighting for justice, survival, and a future untainted by the shadows of the past.
